chore: remove legacy TUI configurator; surface last config gap in GUI (#45)

Audit confirmed the Rich TUI (`meshai --config`) is a strict subset of the
dashboard GUI (covers FEWER sections) and nothing depends on it for bootstrap.
Strip it so the dashboard is the single config surface.

- delete meshai/cli/configurator.py (~1435 lines); cli/__init__ minimal
- main.py: drop --config + run_configurator dispatch (keep --config-file);
  bootstrap log now points to config.example.yaml / the dashboard
- docker-entrypoint.sh: remove the ttyd `meshai --config` block on :7682
  (default-config heredoc + bot exec loop untouched)
- docker-compose.yml + Dockerfile: drop the 7682 port + ttyd install (EXPOSE 8080)
- README / config.py header / config.example.yaml: de-reference the TUI
- drop `rich` from pyproject + requirements (grep-verified unused)

Close the only GUI config gap the audit found:
- Config.tsx weather tab: add openmeteo.url + wttr.url inputs (backend already
  round-trips the nested WeatherConfig dataclasses)

Bootstrap intact: config.example.yaml copy, entrypoint default-config write,
and defaulted Config() when no file exists all remain. `python3 -m meshai`
and `--config-file` unchanged. TS/import validated at Docker build.
